This invention appertains tonew and useful improvements in tooth brushesand more particularly to a tooth brush of the self con-y tained toothpaste supply type.

e An important object ci the invention is to provide a tooth brushwherein the handle thereof is adapted to contain a supply of tooth paste, and which is provided Awith means whereby the toothpaste can bedispensed. very readily.

Another important object of the invention is to provide a tooth brush ofthe character stated.. capable of beingmanufactured at low cost. I

Thess and other'important objects and advantages of the invention willbecome apparent 'to the reader of the following specification andclaims.

ln the drawings Y Figure 1 represents a side elevational view of t lenovel brush structure.

Fig. 2U represents a longitudinal sectional view through the brush.

Fig. 3 represents a side elevational view Fig. 4c represents a. crosssectional view taken substantially on the line. 4.--4 of Fig. 1. Fig. 5xpresents a side elevational view of the no e with the brush removed.

Fig. 6 represents a top plan view of the nozzle with the brush removed.

Fig. 7 represents a top plan view of the brush removed from the nozzle.A

Fig. 8 represents a longitudinal sectional Referring to the drawingswherein like I numerals designate like parts, it can be seen thatnumeral 5 represents a barrel, provided with threads at one end forreceiving the cap 6, .which cap is provided with a central opening 'for'recei the shank 7 of the tube 8, which is located within the barrel 5.The shank 7 extends a substantial distance beyondvthe cap 6 Iand has theknurled collar 9 secured thereon by the pin 10.

The inner end of the tube v8 is provided with a nut 11 through which'the internally and externally three ed sleeve 12 is feedahle when thenut 11 is rotated. The sleeve 12 receives the externally threaded .rc-d13 which lthe barrel 5 opposite to the cap projects from the follower14, the follower being provided with a circumferential packing 15 wipingthe inner side of the cartridge 16, which is shown in detail iii-Fig. 8.

A stop member 17 is provided on the end of 55 the sleeve 12 adjacent thecap 6. The endof v 6 is threaded for engagement into the end portion 18of the nozzle structure 19 which tapers outwardly toward its free end.The under side 00 of the nozzle 19 is reduced and provided with alongitudinally extending channel at each side thereof. The nozzle isalso provided adjacent its outer end with a lip 21 projecting insubstantially parallel relation to the portion provided with the channel20. It can also be seen, that the, area betweenthe lip 21 and thegroovedv portion is provided with an obstruction 22 and by referring toFig. 2 it can bev seen that the passageway 23 in the nozzle is divertedupwardly as at 24 at this point.

As is shown in Fig. 4, the outer end portion of the nozzle is basinedout as at 25. The brush includes a block 26 provided with asubstantially V-shaped trough 27 therein and the block has openings 28therein extending downwardly from the trough through the bottom of theblock, so that paste in the trough can be forced downwardly against thebristles 29.y

` The block 26 at Vthe upper portion of the trough 27 is providedwitharib 30 which engages into the grooves 20 of the nozzle 19, securing theblock 26 to the nozzle after the reduced portion 31 thereof has beenengaged above the lip 21 of the nozzle.

The cartridge. for containing a. supply of paste comprises the tube 16in which the 90 paste 32 is packed. This tube 'is provided with areadily movable plate 33 while the opposite end is provided with a.stopperv 34 which can be readily removed.

vThis is a manner in w in the cartridge form, and obviously by removingthe stopper 34, the same can be inserted into the barrel 5. It can nowbe seen that when the collar 9 is rotated, the consequent rotation ofthe nut 11 will feed the sleeve 12 10 ch the paste is lsold 95 forwardlyso that the follower-14 will exertitself against the paste in thecartridge 16.-

Obviously, when ,the sleeve 12 has been Y fed to the extent that thestop 17 binds against the nutll, thenut and sleeve will rotate tother.This will rsult in the feeding of t e rod 17, further extending thefollower uns tilx substantially allof the paste has been dis- -pensedfrom the cartridge tube 16.

^ 1 0 While the foregoingciicationsets forth the invention in spec' cterms, it is to be understood that numerous changes in the shape, sizeand materials may be rorted to without departing from the spi-rit andscope Y of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new is:

1. A tooth' brush comprising Aa barrel, a tube rotatably mounted withinthe. barrel, 2Q means at one end of the barrel for rotating the tube,-an internally threaded nut on the tube, an externally and internallythreaded sleeve feedable by the said nut, a follower, a rod extendingfrom the follower and provided with threads to engage with the internaly threads ofthe sleeve, and a brush head a the opposite end `of ithesaid barrel. 2. -A tooth-brush comprising an elongated body, a reducedextension at one end of the v body, a short lip at the same end ofthe-body' in substantiall parallel relation `to the ex'- tension, a brushead including a back,'said, back being engageable against the extensionwith one .end thereof between the extension and the li sald'back beingpel"-y forated and provid with a basin on itsinner side, said extensionrovided at;

its inner side with a groove, an a .chamber in the body 4communicatingwith the ve 40 and basin when the back 1s assembl with the body.'l

In testimony whereofI axmy u ture. HOLLIE L. TB Irl:
